Recent rainfall from a dissipating cyclonic circulation over Madhya Pradesh has left Lucknow with elevated soil moisture and humidity, moderating overnight cooling ahead of September 21. Official IMD forecasts and numerical models project a minimum near 27°C under partly cloudy to mostly clear skies, with light northerly winds limiting advection of cooler air. Clear conditions could enhance radiative cooling toward the lower bins around 26°C or below, while any residual cloud cover or higher dew points would trap heat and support readings near 28–29°C. Model consensus remains tight with limited spread, yet traders assign equal 50% implied probability across bins, reflecting uncertainty in exact cloud timing and boundary-layer moisture during the early monsoon withdrawal phase. Updated evening observations and overnight model runs will likely narrow the range.
